Specification of Letters Patent. Patntcd lll-y 18, 1916.

Application led April '7, 1915. Serial No. 19,649.

To all whom t may concern.' Be it known that I, JOHN P. BEIL, a citizen of the United States of `America, and a resident ofthe county of King and State ofvehicle, or at'will from a point which maybe removed either a short or a considerable distance from thegate, and which may be closed under similar conditions.

The construction and operation of a gate embodyingmy invention has beenshown in the accompanying drawings, and will be described in the specification hereinafter, the particular features of novelty being pointed out in they claims terminating this vspecification. d

In the accompanying drawings I have shown the, constructions which are now preferred by me.

Figure l is an elevation of the gate, the open position beingshown by dotted lines. Fig. 2 is a sectional elevation taken upon the plane indicated by line 2 2 of Fig. 1. Fig. 3 is a sectiontaken upon the line 3-3 of Fig. 1. Fig.4 showsl in detail the upper corner `of. the hinged end ofthe gate, the counterweight s ecured at this point being shown'in section. Fig. 5 shows'the gate in section by a view similar to' that of Fig. 2, and in connection therewith slightly different means for operating the gate. Figs. 6,7 and 8 are respectively'plan and two sectional elevations taken on planes at right angles to each other, of one form of device for operating the gate by the action of wheelsof a vehicle. Figs. 9, 10 and 11 are respectively, 9 and 10, sectional elevations, and 11 a plan of equivalent but slightly dider'ent means for operating the gate by the action of a vehicle. 4

The gate 1 is pivotedto swing upona transversely and horizontally extending pivot axis 10, which is located at yone end of the gate, and preferably-quite close to the lowermost `edge thereof. This pivot axis is supported by two posts, 2, which are separated a suiicient distance to securely hold the gate.

At the upper edge of the gate and at its pivoted end, inclined blocks 11 may be placed at each side thereof, to assist in centrallyf locating the gate between the posts, and also -to prevent undue sidewise 4movement 'of they gate. At the lower edge of the gate brace rods 12 may be provided, one end being secured upon the pivot axis 10 and the other end to the bottom bar ofthe gate. These serve to thoroughly brace the gate.

One of the horizontal bars of the'gate,'as the bar 13, is mounted to have a limited reciprocation. Stops, as 14, limit the projection ofthe bar at the swinging end of the gate. This, end of the bar projecting, as indicated at 15, is intended for entrance within a recess in a post 16. Vhen so projected, vthe gate is locked against movement,

'either horizontally orvert-ically,vand cannot beopeneduntil the bar 13 has been withi drawn. -The bar is normally held.v in pro- ]ected or locking position, asby means of a vspring or springs, ofr which two are shown,

the spring 17 being a coiled spring acting l under tension, and 18 a leaf orplate spring,

secured to the swinging end `edge of the gate, and bearing against the end of th latch bar 13.

After the latch has been released, the gate is swung upward about its axis 10, into the position shown by dotted lines in Fig. 1. To counterbalance somewhat the weight of the gate, I provide one or more counterbalanceweights, as 3, which are supported' by cords 30 or like means, which extend over pulleys 31 carried by the upper ends of posts 2, and thence extend downwardly to an attachment with the gate at 32.

In gates which are longer than their height, such as the gate shown in Fig. 1, the gate, in its closed position, exerts a stronger torque about its pivot than when in its openposition. VTo compensate for this, I secure to the upper part of the gate, in position substantially vertically 4,above its.4

pivot axis, a compensating counterweight 4. This is made in the form of a container or hollow case, within which may be placed shot or other heavy materials, 40, whereby the weight and effectiveness of this compensating balance may be varied to suit different conditions. This is provided with a threaded opening, which receives a thread- -ed plug 41, or other suitable means by which the material may be secured in place therein. I have also shown it as provided with flanges 42 and 43, which engage respectively with 'the top and end edges of the gate, and which are secured by U-bolts 44. This cornpensating counterbalance, being directly over the pivot axis 10 when the longer dimension of the gate is horizontal, is neutral so far as its rotative effect upon the gate is concerned. In this same position of the gate the weight of the gate itself is so disposed as to produce the maximum rotative effect. When the gate is in the open position, wherein its longerdimension is vertical, the rotative effect of the gate proper is much decreased: however, in this position the compensating part 4 is so positioned as to exert its maximum rotative effect. lVith the weight of this compensating part properly proportioned to the weight of the gate, the combined rotative'eect may be equalized for each of these positions.

The counter-weight L performs two functions; irst that purely of a counterweight which has just been described. In addition it serves as a stop and a striking member for the corner of the gate to resist the shock incident upon the stoppage o f the gate when it reaches its forward opening position. In this position this corner of the gate rests upon the ground, or some object supported from the ground. In co-ming down to this position there is apt to be more or less shock. A gate of this kind which is not reinforced at this corner is likely to become racked and in time wrecked. The counterweight 11 projecting in the direction of the Alength of the gate is certain of contact with the ground before any other part of the gate, and being provided with lianges which extend over the top and side surfaces of the gate and which are strongly secured thereto, very materially adds to the stiffness of the gate.

A cord or cords 5, are secured by one end to the gate at a point, sufficiently removed from both the botto-m edge and the end edge which contains the pivot 10, that in each position of the gate, this point of connection is removed laterally from the post upon which the pivot is supported. This cord or cords 5, extend upwardly over guides, as the pulleys 50, and then away from the gate to such distance as may be necessary and suit the purpose desired. In Fig. l I have shown the cord 5 as extendedy toand fastened at the upper end of a post 6, which post is at such distance from the gate as would permit a person seated in a vehicle approaching the gate to grasp the depending cord 51, which is secured to the cord 5, and pull down thereon. Such a pull producesa lateral deflection o f the cord 5, and an upward pull upon the end thereof which is attached to the gate, thereby giving the gate an upward impulse, which, if it is unlocked, will cause it to swing up, until its center of gravity has passed beyond its pivot, whereupon it will settle into the position shown by dotted lines in Fig. 1. If, however, the gate is in the open position, as

shown by dotted lines, it will be rocked upon its pivot until it swings downward into the closed position.

The operating cord 5, instead of being connected directly7 with the gate, is connected with a bal: or link GG which is pivoted to the gate a1: 32. In the locked position of the gate, this bar is deliected from a straight line, and away from the pivot end of the gate, by engagement with a pin ('31, carried by the reciprocating latch bar 13. This deflection is produced by the action of the spring or springs 17 18, which act upon said latch bar to hold it in locked position. The strength of these springs should be suflicient to overcome the horizontal effort due to the deflection of the cord 5.

y The first result caused by a pull upon the cord 5, is a withdrawal of the latch bar 13 and the unlocking of the gate. Following this the gate is raised. The linkGG is free to move away from the pin G1 in one direction, which occurs after the gate has been raised to a certain angular position. This link will therefore, assume the position shown by dotted lines in Fig. 1, when the gate is open. In this position the latch bar 13 will be supported by the springs 17, 18. Excessive movement of the latch bar toward the rear end of the gate may be prevented by an additional stop 19.

It is possible to extend the operating cord or wire to a considerable distance from the gate, should this be desired. This may be done by extending the cord 5 directly to said distant point; or this extension may be a separate cord or wire 52, which may be conveniently supported upon as many posts 53 as may be necessary to properly sustain it. It has a sliding or freely movable support with these posts. It may be provided with a stop 54, engaging with the last post of the series, to limit its movement toward the gate, and be provided with a handle, as 55, by which it may be engaged to operate it. At the gate, this cord or wire 52, would pass over an elevated guide 57, thence downward about a guide 56, located a suitable distance beneath the cord 5, and thence upward to a connection with said cord 5. It should also, preferably, have connected therewith an offset tensionl cord 59 and weight 58, to maintain sutlicient tension to properly sustain the wire 52 between its supports.

In Fig. 2 I have shown the operating mechanism as consisting of the parts described in duplicate, these being at each side of the gate, and employing two posts 2, one at each side of the gate.

In Fig. 5 I have shown only one of the posts 2 extending to any appreciable distance above the top of the gate. The other post 20 need extend only sufficiently high to engage the spacing blocks 11, at the top edge of the gate. In this figure the cord 5, by which the gate is operated, extends along the ground, or just above the ground, andv run of the wire 52. In Fig. 5 I have also shown levers 21, pivotally mounted on the upper ends of posts 22, located near the gate. The operating cord 5 is directly connected with one end of these levers, while the depending cord 51, which is engaged by the hands in operating the gate, is connected with the other end of the lever. This same end of the lever may be connected by a cord 23, with the cord or wire 52, which extends to the distant operating position. In Fig. 5 I have indicated, at 7, a device by which the gate may be operated by a vehicle. One type of this device is shown in Figs. 6, 7 and 8, and a modification thereof in Figs. 9, 10 and 11. This comprises two boards 70, placed in alinement, their meeting ends being supported on a block 71, which is in turn supported upon a lever 72, which is pivoted at 78, and at its other end has. the cord 74 connected thereto and extending upwardly and over a guide pulley 75, and thence extending to the gate and connecting with or substituting for the cord 5, previously described. The meeting ends of the boards 70, are normally slightly raised. A vehicle running upon these planks will depress this end, and cause the lever 72 to be depressed, thereby exerting a sudden pull upon the cords or wire connecting it with the gate. This device should be duplicated at each side of the gate, the one which is placed where it is engaged before reaching the gate, serving to open the gate, and the one beyond the gate serving to close the gate after the vehicle has passed through.

The modified construction shown in Figs. 9, 10 and 11 substitutes a rocking bell-crank lever 8 for the pulley 7 5, th-e swinging end of the lever 72 resting upon one branch of the lever 8, and the cord or wire 74 being connected with the other arm.

Having now described my invention, what I claim and desire to secure by Letters Patent of the United States is:

1. In combination, a gate, an operating means therefor employing a cord or like strain conductor, two elevated supports for said strain conductor near the gate, but sep arated from each other, the end of said strain conductor distant from the gate being anchored, a second strain conductor connected to the first named between its said supports, and a guide for said second strain conductor located laterally from its direction of extent, and other guides for said last named strain conductor leading it to a distant point.

.2. In combination, a gate, an operating means therefor employing a cord 'or like strain conductor, two elevated supports for said strain conductor near the gate but separated from each other, the end of said strain conductor distant from the gatebeing anchored, a second strain conductor connected to the first named between its said supports,l

and a guide for said second strain conductor located laterally from its direction of extent, other guides for said last named strain conductor leading it to a distant point, and a tensioning weight connected with the end of said last named strain conductor adjacent the gate to normally relieve the first named strain conductor of the pull thereof.
